Had I been giving a history lesson I would have mentioned these facts. However as I was merely replying to John Smiths assertion that Macbeth was a fictional character there was no necessity for such a detailed response. Merely noting that Macbeth existed, had been King of Scotland and the play had been broadly based on events in his life is enough.
'Broadly' is generous.
Shakespeare was reinforcing James's right to rule (which was precarious anyway, given the Tudors themselves, before the Stuarts, were usurpers, the last of which, Elizabeth, had declared James her heir almost on her deathbed) by casting Macbeth as a weak schemer who took advice and was manipulated by women (even witches) into poisoning his rivals and enemies instead of taking the manly course of challenging him in battle (which is in fact what Macbeth did).
The agony of Gruoch with her guilt and suicide was to reinforce that Macbeth was not the rightful king of the Scots (which he was).
Given the Stewards, then Stewarts, then Stuarts were descended from Malcolm's family, it was a smart move by Shakespeare to cast Macbeth as weak, evil and craven.
Exactly what Shakespeare had done to the Plantagenets in favour of the Tudors by casting Richard III as weak, evil and craven and a child killer.
